Can't see the point, a turbo for each two cylinders doesn't seem worthwhile, especially, when displacement would drop and so will engine pulses, plus a complex manifold followed by tight space. I did read about a scroller setup someone did in the USA, even then the results weren't any better than just a single big turbo setup.
can someone just explain this to me... how would displacement drop? and engine pulses?
4 Cylinders, each time the exhaust valves open on that cylinder it sends the exhaust gases flying through at a higher speed, this is a pulse, imagine in a 4stroke the pulses are 180degrees apart. So 4 pulses every two rotations. These exhaust gases are what drive the turbo. Now imagine only two cylinders doing this. Even less gases pushing the turbine (imagine a pushbike where you was using bot feet to peddle, but now the person is using just one foot to peddle instead of two to drive the wheels).
Now you have an engine with 1800cc displacement pushing one turbo, if you have two turbo's in a parallel setup like you see in v6TT/v8TT engines you now end up with a setup where you have two turbo's for 900cc each, and you only have 900cc of displacement pushing each turbo at a less frequent rate in layman's terms.
Thats the theory, correct me if I'm wrong.
